Swarm cases

receipt 16580: PRR5 in dopamine neurons, braak

power
full sample -0.35 (p 0.156, n 18), 95% CI -0.70 to +0.14. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.34 (p 0.161, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.38 (p 0.116, n 18). could be the mix.
skeptic
leave-one-out range -0.47 to -0.26, sign flips 0; without severely affected donors -0.35 (p 0.156, n 18). fragile.
cell type
strongest in microglia: -0.65 (p 0.0036, n 18) vs -0.35 in dopamine neurons. proposing microglia.
axis
no measure beats "tracks Braak Lewy-body stage" for PRR5 in dopamine neurons.

follow-up registered; not confirmed in substantia nigra, an independent cohort.
